Step 1: Complete the First Mission in Luigi’s Mansion 3

Here’s a step-by-step walkthrough on how to complete the first mission. This is how you can quickly to unlock co-op and Gooigi.

First, watch the intro cutscene. Then run away from King Boo and follow Polterpup. When you arrive at the locked door on the second floor, find the key behind the front desk. 

Unlock the door and enter. After the cutscene, go to your left and enter another door. Go past the locked metal door. Find another key behind the first door in the hall on your right. 

Direct the light of your flashlight at the mirror, and the key will appear. Go back to the metal door and unlock it. Open the vault using your flashlight. Foloow Professor E. Gadd’s instructions. 

Now take the elevator to the underground garage in B1. Defeat the ghost in the garage and go back to the elevator. Activate the E. Gadd hotline in the game’s menu, and press the F5 button. 

Follow the marker on the map, and defeat another ghost before going back to E. Gadd in the garage. 

Step 2: Activate 2-Player Co-op

After completing the first mission, you can finally play co-op with a friend. Here’s how to do it:
